(Vector) Glueballs and Charmonium Decay Revisited

Abstract

From the $0^{++}$ glueball candidate we argue that the $1^{--}$ glueball $O$ to be near in mass to $J/\psi$. This is supported by the recent null search for $\psi^\prime \to \rho\pi, K^*\bar K$, while absence of distortion in the energy scan of $J/\psi \to \rho\pi$ indicates that $\Gamma_O \gg \Gamma_{J/\psi}$. $O$ may also play a role in the OZI violating $\bar p p \to \phi\gamma, \phi\pi$ production puzzle.
